Letters Patent No. 110,728, dated January 3, 1871.

IMPRQVEMENT 'I N SASH'HOLDERS.

The Schedule referred t'c in these Letters Fatent and making paxt of thesame.

accompanying drawing and the letters of referencemarked thereon, to be afull, clear, and exact description of the same, and which said drawing,-constitutes part of this specification, and. represents in- Figure 1 aside View of the holder, as applied to the door of a carriage;

Figure 2, a front view of the holder detached;

Figure 3, the bearing; and

Figure 4, the cam detached; and in Figure 5, a cent-ral section on linea: x of iig. 2.

This" invention relates to a device for holding or supporting the sashof carriage-doors, and to prevent the rattling of the same in anyposition; and

The invention consists in a cam, constructed as hereafter described, andapplied to the door to'bear against the sash, to hold itpto any desiredelevation and with sufficient force to prevent the rattling of the sash.

A is a portion of the door.

B, the sash, represented as partially raised from the pocket.

C, the cam or holder, '1s formed as seen in iig. 4.

D is a circular central portion from which the cam C projects, andfromthe opposite side an arm, E, by means of which the cam is operated.

The central portion D is made hollow, so as to form a chamber, a, (seeiig. 5,) the chamber' being a complete circle, as seen in iig. 4, andthis part is itted Onto a plate, F, (see fig. 3,) which plate closes thechamber,`as seen in iig. 5.

The cam is secured to the plate F by a screw, Gr, 'so that the cam willturn freely on the plate F.

'lhe said plate F forms the bearing for the earn. Within the chamber a acoil spring, el, is arranged to act upon the cam to throw it forward.

To secure the device to the carriage-door, the plate F is fixed to ormade a part of the flange H, (see figs. 2 and 3,) and through the saidflange screws are 'inserted into the door.

Placed upon the door, as in 1, when the sash is raised, the cam bearsoutward upon the sash, so that the Weight of the sash tends to draw thecam harder against the sash, and thus support it in any desiredposition, and in so rm a manner as to prevent rattling.

The sashcan be freely raised with the cam bearing v thereon to anyposition; hut to drop the sash, press down the arm E to draw the camfrom the sash, as denoted in broken lines, tig. 1; then the sash willdrop of its own accord.y

When the sash is dropped into the pocket, the holder will, if notprevented,`throw outward so far as tol interfere with thera-ising of thesash, and at other,

times it may be desirable to hold the cam back from the sash. To do thisl fix a loop, I, to the arm E, and a stud, L, upon the carriage door, sothat when desirable the cam can be drawn back, as denoted in brokenlines, and the loop I caught upon the stud L. Any other mode may beemployed.

To prevent injury to the sash, as well as to hold it lnore securely, Iarrange upon the face of the cam a pad of India-rubber, or other similarflexible niaterial. Y

I do not wish to be understood as broadly'claiming a cam constructed soas to bear against the sash for its support, 'as such is not new; but

I claim as my inveution- I v A sash-holder, consisting of the plate F,formed upon or made a part of the plate H, aud combined with the cam C,formed upon the central chambered portion D, the arm E, and springwithin the chamber, the whole constructed and arranged to operatesubstantially in the manner set forth.
